Well first you do 6÷3=2. Then you do 2*5= 10. Also do 20+10=30-15=15. So your answer is 15

olasank [31]

1/2 gallon= .75 grams
1 gallon= 1.5 grams
2 gallons = 3 grams
4 gallons = 6 grams

So

4 gallons is 6 grams
Then we add on a half which is .75 grams

6g + 0.75g = 6.75g

Hope that helps ;•)

Answer:

y = -x +3

m = -1

b = 3

Step-by-step explanation:

To solve the given equation for y, divide by the coefficient of y.

(-3y)/(-3) = (3x -9)/(-3)

y = -x +3

The slope is the x-coefficient, M = -1.

The y-intercept is the added constant, B = 3.

Both equations are graphed in the attachment. Texture has been added to the original so you can see the graphs are the same line.

Answer:

The answer is "0.68".

Step-by-step explanation:

Given value:

$X_i \sim \frac{G_1}{2}$

$E(X_i)=2 \\$

$Var (X_i)= \frac{1- \frac{1}{2}}{(\frac{1}{2})^2}\\$

$= \frac{ \frac{2-1}{2}}{\frac{1}{4}}\\\\= \frac{ \frac{1}{2}}{\frac{1}{4}}\\\\= \frac{1}{2} \times \frac{4}{1}\\\\= \frac{4}{2}\\\\=2$

Now we calculate the $\bar X \sim N(2, \sqrt{\frac{2}{n}})\\$

$\to \frac{\bar X - 2}{\sqrt{\frac{2}{n}}} \sim N(0, 1)\\$

$\to \sum^n_{i=1} \frac{X_i - 2}{n} \times\sqrt{\frac{n}{2}}} \sim N(0, 1)\\\\\to \sum^n_{i=1} \frac{X_i - 2}{\sqrt{2n}} \sim N(0, 1)\\$

$\to Z_n = \frac{1}{\sqrt{n}} \sum^n_{i=1} (X_i -2) \sim N(0, 2)\\$

$\to P(-1 \leq X_n \leq 2) = P(Z_n \leq Z) -P(Z_n \leq -1) \\\\$

$= 0.92 -0.24\\\\= 0.68$
